lf/l VEN Tl? ALEXANDER EoeDANEEv, or NEW YORK, N. Y.

` CORK-BLOCKING MACHINE.

To all whom t may concern:

Be it known that I, ALEXANDER Boo- DNEFY, a subject of the King ofHungary, and a resident of the city of New York, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Cork-Blocking Machines, of which the following is a specification. l

The present invention relates to an improved apparatus for cutting orblocking out corks from cork strips.

More particularly it relates to cork'blockers of the automatic type.machines of this character are usually provided with a tubular knife orcutter in combination with a work support, the latter having automaticfeeding devices for intermittently advancing the cork strips within thereach of the knife. As corks of different diameters are being cut, theknife obviously has to be replaced. On the other hand, the position ofthe work support in relation to the knife must be adjusted to correspondto the diameter of the knife, that is to say the work support must belowered orraised.

The stroke of the feeding device must also be varied, it being obviousthat the stroke must be larger if corks of larger diameters are to beblocked, and smaller if smaller corks are to be cut. The feeding deviceusually comprises a reciprocating bar provided with fingers, saidreciprocating bar being actuated, for instance,by an oscillating arm.AIn constructing the machine, this arm must have a swing that willpermit it to go beyond the largest knife. Owing to this arrangement, theends of the .cork strips will bewasted if small corks are being cut, thefeeding fingers carrying them beyond the knife. Another defect of thecork blocking ma-V 'chines heretofore in use consists in that thelfeeding fingers or other feeding devices contact either with the upperor lower faces of the cork strips as they are being advanced on the worksupport. These faces are very uneven, and for this reason Athe feedingof the strips irregular. Y

It is now one of the objects of the present invention to obviate thesedefects, that is to say to produce a feeding device which car-y riesthecork strips on the work holder in relation to the cutting edge of theknife irrespective of the diameter of the latter always to a fixed pointfrom said edge, and which acts upon the` sides of the cork strips,thatis to say upon the smooth faces thereof, thereby Specification ofLetters Patent.

reducing the waste to a possible minimum and resulting in an evenfeeding of the same.

Another object of the invention is to devisefa cork-blocker which issimple in construction, eificient in operation, and the parts of whichcan be adjusted by a single setting when a knife isreplaced by one ofanother diameter.-

A Yfurther object of the invention is to provide the blocker with acutter in combination with bearings which reciprocate with the cutterarbor1 thereby preventing the oil or other lubricating materiall frombeing ejected from the bearings, a feature common in blockers heretoforein use.

Vith these and .other objects in view, which will more fully appear asthe nature of the Vinvention isf better understood, the same consists inthe combination, arrange- Inert and construction of parts hereinafterfully described, pointed'out in the appended claims and illustrated inthe accompanying drawings, it vbeing understood that many changes may bemade in the size and proportion of the several parts and details ofconstruction within the scope of the ap-l pended claims withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawings, the numeral 2O indicates the mainframe of the machine.On this frame are formed bearings 21, each provided with a. liningsleeve 22, in which is rotatably mounted the main driving shaft 23 ofthe machine. To this shaft rotation may be imparted in any suitablemanner, for instance there may be keyed to the same a.

pulley 24, over which runs a belt that is geared to any suitable sourceof power. c,In the upper portion of the main frame 20 is formed ahorizontal slideway 25, in which is reciprocably mounted a bearing block26, carrying above each other two sets of bearings 27. In these bearingsare rotatably journaled two parallel horizontally disposed tubulararbors 28, to each of which is flxedly attached a pulley 29. The twopulleys are staggered, the belts running over the same being actuated bya single pulley that is carried by a countershaft or other rotary means.The pulleys are provided with sleeve-like extensions 30, each of thepulleys abutting against one bearing of a set and the sleeve-likeextension 30 attached thereto to the other bearing of the set, therebypreventing the tubular arbors 28 from moving in the direction of thelongitudinal axes thereof in relatiorrto the bearings. The bearings maybe lubricated in any suitable manner (not shown in the drawings). Intoeach tubular arbor extends a stop 3l, for instance a spindle, that isfastened in any suitable manner, for instance by a screw 32, to the mainframe of the apparatus. To each arbor is secured, for instance by screwthreads, a tubular knife or cutter 33, within which is loosely held anejector 34, in the form of a rod, that is adapted to bear against itscorresponding stop 3l as will appear hereinafter. The bearing block 26is reciprocated by means ofl a cam 35, that is lixedly secured tothemain driving shaft 23 and provided with a cam groove 36, into whichextends a roller 37, that is carried by one end of a lever 38, thelatter being pivoted at 39 to the main frame and being forkshaped at itsother end, as clearly shown at 40, said fork-shaped end engaging with aroller 41, which is mounted upon the bearing block 26.

Upon two of the lining sleeves 22 is oscillatably mounted a framei 42,its sides 43 abutting against two of the bearings 21, whereby the saidframe is prevented from moving in the direction of the longitudinal axisof the main driving shaft. This frame extends up to a slight distancebelow the lower cutter of the machine, and is there provided with aforwardly extending projection 44, carrying upon each of its sides alatch 45, that is adapted to engage with a projection 45 on the mainframe, said latch mechanisms being' normally in engagement with the saidprojections to prevent a tilting of the frame 42. This frame is providedwith two dove-tail grooves 46, which are disposed parallel to each otherin a plane at 45O to the horizontal plane. Into these grooves reach thedove-tails 47 of a. frame 48, which carries the work-holder and thefeeding mechanism of the device. The frame 48 is provided with adownwardly projecting lug 49, in which is rotatably mounted a spindle50, provided with screw threads 51, meshing with those of a screwthreaded hole 52 in the frame 42. The spindle 50 is also disposed at anangle of 45, and provided at its outer free end with a hand-wheel 53. Byrotating the handwheel 53 the frame 48 will move up or down in thedove-tail grooves 46'of the frame 42, that is to say it will be raisedor lowered, as the case may be, and simultaneously moved forward orbackward in relation to the frame 42. The purposeof this arrangementwill be described hereinafter.

The work holder of the device comprises two horizontally disposed platemembers 54 and 55, which are attached in any suitable manner to thevertical side walls 56 of the fralne 48, the plate 54 with partshereinafter to be described forming the bottom of the work holder forthe lower knife 33, and the platel 55 with the parts carried there` byand hereinafter to be described forming the bottom of the work holdercoperating with the upper knife 33. 'A third -horizontal plate, denotedby the numeral 57, connects the top of the side walls 56 of the frame48, the distance between the plates 54 and 55 being equal tothe'distance between the latter plate and the plate 57. In the upperfaces of the plates 54 and 55 are provided groovesv 58 and 59, and ineach of these grooves is disposed a strip 60,-which extendssubstantially throughout the length of its plate and projects asubstantial distance in rear thereof beyond the cutters 33, as clearlyappears from Fig. 2 of thedrawings. These strips formthe actualsupportsfor the cork strips. The "plate members 54, 55 and ,57

are embraced by two box-like frames 61, one on each side of theirlongitudinal center lines, the latter coinciding with those of thestrips 60. Each frame 61 consists of a top plate 62, that is disposedupon the plate member 57, a bottom plate 63 abutting against theunderface of the plate member 54,v said top plate and bottom plate beingconnected by a vertically extending front post 64 and by a rear post 65.The front and rea'r posts are furthermore each connected by two verticalwalls 66 and 67 the vertical walls 66 being disposed between the platemembers 55 and 57, and the vertical walls 67 between the plate members54 and 55. These two frames are held stationary on the plates 54, 55 and57 at equal distances from the longitudinal center lines of these threeplate members. The distances may be adjusted according to thethicknesses of the cork strips to vbe worked upon. Between each verticalwall 66 and 67 and the adjacent side walls 56 of the frame 48 isdisposed a slide 68, each slide being adapted to be moved toward andaway from the juxtaposed vertical walls 66 or 67 by means hereinafter tobe described. Each slide 68 is provided with horizontal guideways 69, inwhich are seated the guide strips 70 of a vertically disposed feed plate71, each plate being normally located a substantial distance from theinner face of the corresponding vertical wall 66 or 67, and beingprovided with a plurality of horizontally disposed feeding racks 72,which are adapted to project through longitudinal slots 73 in thevertical walls 66 and 67. The feed plates 71 are moved by meanshereinafter to be described in parallel relation to the longitudinalaxes of the strips 60, and furthermore with the slides 68 toward andaway fro-m the said longitudinal center lines. Between the verticalportions 74 of each slide 68 and the corresponding feed plate 71 isdisposed a plurality of blade springs 75, to give the feeding rackssomeresiliency so as to pre- 'vent binding if acork strip of somewhatthicker size happens to come upon the worksupport. In each of the frontposts 64 is formed a vertically extending recess 76, and in each of therear posts 65 a similar recess 77. In each of the recesses 76 isslidably disposed a bar 78, and in each of the recesses 77 a. bar 79. Inthat face of each of these bars which abuts against the correspendingslide 68 are provided two parallel curved substantially obliquelyrunning grooves 80, in which are seated anti-friction rollers 81, thatare carried by lugs 82, the latter being attached to the slides 68. Thegrooves 80 in those bars 78 and 79 which are disposed on the same sideof the longitudinal center lines of the strips 60 run in the samedirections, and so also the grooves in the bars onthe opposite side ofthe said center lines, but the grooves in bars locatedy at opposingsides of the said center lines run in opposite directions, whereby, asthe four bars are simultaneously reciprocated, j

the slides 68 and the parts carried thereby will move toward and awayfrom said centerl lines. The bars are slidably pivoted to spindles 83,which are fixedly attached to a sliding head 84, the latter beingreciprocably mounted upon the frame 48. The sliding head is providedwith a downwardly extending vertical extension 85, carrying a lug 86, onwhich is mounted -an anti-friction roller 87, the latter extending intothe cam groove 88 of a disk 90, that is fixedly at-` tached to the maindriving shaft 23. The extension 85 is made, for a purpose hereinafter tobe described, of .two sections, denoted by the numerals 91 and 92, whichoverlap each other and are separated n aline 93, that runs at 45O ltothe horizontal Y line in the same manner as the separating line betweenthe frames 42 and 48. The sections 91 and 92 are unitedfby a screw bolt.94, that is secured to the ,section 91 and extendsinto a slot 95 in thesection 92.y The slot 95 runs at 45O to the horizontal line. A nut 96,bearing against kthe section 92, serves to hold the two partsoftheextension 85 together. The cam groove 88 comprises four distinctparts, each extending throughout an are of o. From point I to point l1of this groove the sliding head is kept stationary, from point 11 topoint III it is raised, from point IIT to po-int 1V it is again keptstationary, and from point IV to point l it is lowered. When the slidinghead is raised,the slides 68 move away from each other. They are keptstationary while the cam disk 90 makes a quarter of a turn, and aremoved toward each another during a further quarter of a turn of the camdisk while the sliding head moves downward, and kept in their innerpositions stationary through a further quarter of a turn of said disk.

The feeding racks are actuated in the following manner: To each feedingplate 71 is` lixedly attached an outwardly extending pin 97. These pinsextend into two vertically disposed brackets 98, the base plates 99 ofwhich are dove-tailed and slidably disposed in dove-tailed grooves 100in the bottom plates 63 above mentioned. The base plates 99 carrydownwardly extending fork-shaped lugs 101, in engagement with a spindle102, which is keyed to a bellcrank lever 103. This bellcrank lever isfulcrumed at 104 in theframe section 48, its arm 105 carrying ananti-frictio-n roller 106, that is in contact with a slide 107. Thisslide moves in vertical guideways 108 in one of the sides of the framesection 48. A lug 109, in the form of a screw, is carried by the slide107, and ex 48, said lug` and slot predetermining the lowermost positionof the slide 107, and thus the stroke in one direction of the feedingracks. The slide 107 coacts with an eccentric 111, the said eccentricbeing, for instance, made integral with the cam wheel 90 abovedescribed. The eccentric 111 comprises, like the cam groove 88 abovementioned, four sections. From point I to point II the slide 107 islowered, from point I1 to point III it is stationary, the lug 109resting then on the lower edge of the slot 110; from point III to pointIV the slide is raised, and from point IV to point I it is again keptstationary. From Fig. 10 of the drawings it appears that those points ofthe cam groove 8S and of the eccentric 111 which are located on the sameradii are denoted by the same Roman numerals. Bearing this in mind andcomparing the motions of the sliding head 84 and the slide 107, it willappear that whenever the sliding head is in motion, the slide'107 is atrest, and vice versa. It also appears from an inspection of thedrawingsthat when the slides 68 move toward each other and thereby cause thefeedingl plates also to move in the same direction, the feeding racks donot move in the direction of the longitudinal axis of the work-support;when, however, they have reached their innermost positions and theslides 68 are kept stationary, the feeding racks are moved toward thecutters a predetermined distance, that is to say until the lug 109 restsupon the lower edge of the slot 110; and when the slides 68 recede fromeach other, the feeding racks do not move in the direction of thelongitudinal aXis of the work-support, and, finally, when the slides 68are kept stationary in their outermost positions, the feeding racks aremoved away from the cutters a distance depending upon the throw of theslide 107. The brackets 98 are engaged by springs 112, which areattached to the slides 68. These springs cause the racks to move towardthe cutters, and at the same time keep the antifriction roller 106 incontact with the slide 107.

In the rear posts 65 are formed horizontal guideways 113, in which areslidably disposed gripping jaws 114 in the form of box-like structures,one being associated with each of the posts 65. Each jaw 114 carries twolugs 115, having anti-friction rollers 116, which are seated in grooves117 in the bars 79. The grooves 117 in each bar run parallel to eachother and are substantially obliquely arranged; they are, however,inclined in a direction opposite to that in which the grooves 80 abovedescribed run. For this reason, obviously, the jaws 114 move indirections opposite to those of the vslides 68,that is to say wheneverthe'slides move toward eachother, the jaws recede,

and when the slides recede, the jaws move toward each other. In thosewalls of the jaws which face each other, that is to say in those whichare arranged in alinement with the walls 66 and 67 above mentioned,there are detachably held two plate members 118, each being providedwith two circular apertures 119 in vertical alinement with each other.The apertures of each set in one plate 118 register with thoseot theother and are in alinement with the tubular cutters 33. The aperturesare of a somewhat larger diameter than the outer diameters of thecutters, and must, obviously, be replaced when the cutters are exchangedfor larger or smaller ones. In Fig. 18 one of these plates is shown,illustrating diagrammatically the manner in which the apertures in a seto` plates are disposed. From this figure it will be observed that theapertures all contact with a vertical line 120 and also with ahorizontal line 121, their centers being disposed on a line 122, thelatter running at 45O through the meeting point of the lines 120 and121. The purpose of this arrangement will be explained hereinafter.vAround the apertures 119 are formed upon the inner faces of the platemembers 118 ring-like milled projections 123, which contact, when thejaws are in their innermost positions, with the cork strip, and keep thesame in position during the cutting operation.

With each strip 60 is associated a presser foot 124. These presser feetare ixedly attached to rock-shafts 125 and 126, which are journaled inthe sides 56 of the frame section 48. The presser feet are somewhatresilient, and their foot portions 127 are adapted to engage the tops ofthe cork strips upon the work-support. To the rock-shafts 125 and 126are iXedly attached levers 128 and 129, respectively, which are pivotedto links 130, the lower ends of which are pivoted at 131 to levers 132,the latter being ulcrumed at 133 to the sliding head 84. The pivots 131move in registering arcshaped slots 134 in the sliding head 84 and inthe side plates 56 orn the frame section 48. To the frame section 42 arefulcrumed at 135 levers 136, that carry at their free ends a spindle137, that is seated in slots 138 in the levers 132. The said spindle'isalso seated in slots 139 in the side walls 56 of the frame section 48.henever the sliding head 84 moves upward, the presser feet are caused tomove into contact with the cork strips by means of the connectionsabo-ve described; that is to say when the sliding head moves upward, thelevers 132 swing around the spindle 137, their pivot spindles 131 movingin the arc-shaped slots 134 downward, and causing thus the presser feetto move into contact with the cork strips. rIhe presser feet' aresomewhat resilient to adapt them to the irregularities of the upperfaces of the cork strips. Inasmuch as the presser feet are actuated bythe sliding head lin the manner above indicated, it will be obvious thatwhenever the jaws 114 move into contact with the cork strips, thepresser feet are depressed, and when the said jaws recede from eachother, the presser feet are lifted. However, the presser vfeet engagethe cork strip previous to it being gripped by the jaws 114, that is tosay they are forced onto the supportingstrips 60 before they are grippedby the jaws above mentioned. v

To the projection V44 of the frame section 42 are attached below thecutters 33 an inclined plate 140, and in rear of the strips 60 aninclined plate 141. The inclined plate 140 directs the corks into areceptacle placed in rear of the machine, and the inclined plate 141 thewaste into another container.

The operation of this deviceV is as follows: In the positions of theparts shown in the severaliigures of the drawings the sliding head84 isshown in its uppermost position. Vhen in this position the gripping jaws114 are in engagement with the sides of the cork strip, and the presserfeet held against the upper face of the latter. The slides 68 and thusthe feeding racks are in their outermost positions in relation to thelongitudinal axis of the work-support. The cork strips are placed uponthe supports, that is to say upon the strips 60, and advanced manuallyuntil they are withinthe reach of the feeding racks.' When vthe slidinghead is in its upper position, it stops there during a quarter of a turnof the main driving shaft 23, and during this time the cam 35 moves thebearing block 26 toward the work-support, whereby the cutters block outcorks from the strips on the support. From this it will be observed thatduring the cutting operation, the gripping jaws and the presser foothold the cork strips against motion. Vhile the cutting operation takesplace, more particularly during the'time the gripping jaws and thepresser foot hold the cork strip against movement, the slide 107 israised, whereby the feeding racks move away from the cutters. During thenext quarter of a turn of the main driving shaft, the sliding head 84 islowered, thereby bringing the feeding .racks into engagement with thecork strips. During the same time the gripping jaws recede and thepresser foot is lifted, and the cutters are withdrawn from the cork. Therods 34, in abutting against the stops 31, eject the corks from thecutters. During the neXt quarter of a turn of the main driving shaft,the sliding head 84 is kept in its lower position stationar thle springs112 are adapted tofact on the feeding racks, which will move the corkand :the slide 107 is lowered, whereby strips a predetermined distancetoward the cutters. The sliding head moves then upward, causing thegripping jaws and the presser foot to engage the cork, and at the sametime the slides 68 to move away from the cork strips. The cycle ofoperation now described is then repeated. V

In the drawings the parts of the machine are shown in the positionswhich they occupy when cutting corks of the smallest diameter. If corksof a larger diameter are to be cut, first of all the cutters 33 aremoved into their outermost positions, in which they clear the grippingjaws. The latches 45 are then disengaged from the'keepers, and the frame48 with the parts carried thereby swung'around the main driving shaft 23in the position shown in dotted lines in Fig. 21, after which thecutters are removed from the arbors 28, and replaced by those of thedesired larger diameter. The plate members 118 are thentaken off thegripping jaws, and replaced by those having openings corresponding tothe diameters of the knives. The frame sections 48 and 42 are then swungback into their normal Positions, in which the latches 45 are engagedwith their keepers. The nut 96 is then loosened, and the hand-wheel 53turned until the tubular cutters are properly in alinement with theapertures 119 in the plate members 118. After this the nut 96 istightened, to properly connect the two sections of the eXtension 85 ofthe sliding head. Due to the fact that the frame section 48 slides onthe frame section 42 under an angle of 45, by the above describedoperation the frame section 48 will be lowered in relation vto the framesection 42, and simultaneously moved away from the cutters the samedistance (see position shown in dotted lines in Fig. 22). The adjustmentis in all cases such that the lines 120 and 121, shown in the diagram inFig. 18 of the drawings, always contact with the edges of the cutters.It is tov be observed that the feeding racks in their movement towardthe cutters stop always at the very same point, and it is only the throwin the opposite direction which is varied by the setting abovedescribed. For this reason naturally the cork strips are moved apredetermined distance toward the cutters, and distances ,between thecuts are always the same, no matter whether corks of larger or smallerdiameters are being blocked, and the cork strips are fed up to theirvery ends to the cutters, so that the wasting of material is effectivelyprevented.

It is to be observed that, asthe frame section 48 and the parts carriedthereby are lowered and removed from the centers of the cutters for thepurpose above described, the distance between the spindles 133 and 137will be enlarged for the reason that the ilo spindle 137 is carried bythe levers 136, 130

which are fulcrumed to or stationary part of the frame. For this reasonthe arc through which the pivots 131 are swung is decreased and so alsothe swing of the presser foot. This is necessary for the reason thatcorks of larger diameters are cut from wider strips.

Attention is called to the fact that the slide 107 in its lowermostposition does not contact with the eccentric 111. When the frame section48 and the parts carried thereby are lowered, as above described, theslide 107 is brought nearer to the eccentric 111. As now this eccentricturns, the upward throw of the slide 107 will be naturally greater, andthereby also the backward movement of the feeding racks. The slide 107is continuously in contact with the eccentric 111 when corks of thelargest diameters are to be cut on the machine.

F rom the foregoing it appears that by turning the hand-wheel 53 in theproper direction, all parts are set according to the diameters of thecorks to be cut. With the hand-wheel 53 can, obviously, be associated agraduated scale. This element has not been shown as the same does notform an essential part of the invention.

The frames 61 must be adjusted in relation to the longitudinal axis ofthe support according to the thickness of the cork strips. These framesmay be clamped in any suitable manner, for instance by means of screws,to the plates 54, 55 and 57, after bringing them to the desiredpositions. The bars 78 and 79 slide on the pivot spindles 83 and thelugs 101 on the spindle 102 of the bellcrank 103.
